Narrative:Due to low oil pressure and high oil temperature the right engine was secured. During the precautionary landing, gear extension was delayed until aprx 800 ft agl. Since the right engine powers the only hydraulic pump, a landing gear down and locked condition was not possible by the normal means. As the gear were extended and hydraulic pressure began to decrease the pilot realized that normal gear extension would not occur. The altitude of the aircraft precluded the emergency extension of the landing gear. Shortly after touchdown on runway 26L the right main landing gear collapsed.
